Distribution of four species of Stenocercus in Ecuador. Forest, and Very Humid Premontane Forest life zones. The mean annual temperature is 24-26 °C in the former two life zones, 24-25 °C in the third and 18-24°C in the latter two. The mean annual precipitation is 125-250 mm in the first one, 500-1000 mm in the second one, 1000-2000 mm in the third and fourth ones, and 2000^000 mm in the lat- ter one.

This species also occurs in northwestern Peru (Cadle, 1991). Stenocercus limitaris Cadle Stenocercus limitaris Cadle, 1998:261. Holotype: AMNH 22183 a male from Alamor, 04'02' S, 80'02' W, 1325 m, Frovincia Loja, Ecuador. Diagnosis.â(1) Maximum SVL in males 97 mm (Cadle, 1998); (2) maximum SVL in females 82 mm (Cadle, 1998); (3) vertebral scales 40-52; (4) scales around mid- body 39-54; (5) internasal scales 4-5; (6) gular scales 17- 23; (7) lamellae on Finger IV 17-23; (8) lamellae on Toe IV 24-32; (9) posthumeral pocket Type 3 or 4; (10) postfemoral pocket Type 4 or 5; (11) projecting angulate temporals ab- sent; (12) one row of enlarged supraoculars more than twice size of scales in adjacent rows; (13) occipital scales large, keeled or wrinkled, juxtaposed; (14) ventral scales mucr- onate, keeled, imbricate; (15) scales on posterior surfaces of thighs mucronate, keeled, imbricate; (16) antehumeral fold nearly inconspicuous; (17) tail strongly compressed laterally; (18) gular region in males not black; (19) dorsum brown in males and females. Stenocercus limitaris is distinguished from other spe- cies of Stenocercus by the combination of keeled ventrals, keeled, wrinkled, or multicarinate large occipital scales, one row of enlarged supraoculars more than twice the size of scales in adjacent rows, two canthal scales, posthumeral pocket Type 3 or 4, postfemoral pocket Type 4 or 5, usu- ally more than 40 sc
